WILLIAM J. JUDD, OF PARKRIDGE, NE JERSEY.

MIXER- SPECIFICATION forming part of Letters Patent No. 775,242, dated November 15, 1904.

Application filed July 9, 1904. Serial No. 215,906. (No model.)

To (all whom, it may concern:

Be it known that LVILLIAH J. J UDD, acitizen of the United States, residing in Parkridge, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Mixers, of which the following is a specificatiom This invention relates to machines for mixing miscellaneous materials, such as mortar, concrete, and other semiliquid or dry materials.

The principal object of my invention is to provide a machine, simplified as to both construction and operation, which will churn or mix the ingredients as long as may be desired and will then rapidly and effectively discharge the mixture. This result has heretofore been obtained by mounting a cubiform or other mixing barrel so that it may be revolved any desired length of time and so that it may be also tilted up in order to dump the finished mixture; but machines of this description have numerous and complicated parts, are expensive to produce, require great care and skill in their management, and are apt to get out of order and require frequent repairs.

\Vhile I preferably illustrate my present improvements in connection with a cubiform mixing-barrel, still any other form of barrel may be used where desired. This mixingbarrel 1 mount so that it revolves upon a single axis, and provision is made whereby its revolution upon said axis effects the mixture of the ingredients for any length of time desired and then quickly drains the mixed contents from the barrel. The mixing is kept up during the discharging operation, and

thereupon the recharging of the barrel may begin instantly, so that the efficiency of the machine is very high, it being practicable to keep the mixing-barrel in operation for many successive charges with hardly the loss of a moment.

Owing to the simplicity of the apparatus, it may not only be manufactured at low cost, but is very compact, which is a desideratum. Moreover, there is little or no liability of a breakdown, which is often a serious matter in the use of prior machines.

Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a plan of a portable mixing-machine made in accordance with my improvements, a boiler and engine being shown for driving the mixing-barrel and a portion of the latter being broken away to disclose the discharging-blades provided thcrewithin. Fig. 9. is a front elevation of the mixing-barrel and its mountings. Fig. 3 is a side elevation showing the discharge end of the mixing-barrel. Fig. 4 is a diagram of the mixing-barrel and a set of discharging blades or buckets therein, the barrel being shown in dotted lines and the buckets in full lines, the position of the parts being the same as at Fig. 3. Fig. 5 shows another form of blade adapted to form a discharging bucket or scoop within the mixingbarrel, this form being provided with flanges for attaching to the sides of the barrel. Fig. 6 is a sectional plan of the mixing-barrel, taken upon the plane of its axis of revolution. Fig. 7 is an elevation of the charging end of the mixing apparatus.

The mixing-barrel is preferably cubiform, comprising six sides, numbered, respectively, 1, 2, 3, 4, 5, and 6. It is mounted so as to revolve upon a horizontal axis, (designated at 7,) said axis intersecting opposite apices of the cube. The purpose of mounting the cube to revolve in this manner is to secure rapid and thorough mixture of the ingredients therein. At the apices referred to the cube is of truncated form and abuts against disks or wheels 8 9. The cube is partially closed by and attached to the wheels, between which it is supported. The intersection of the cube sides with the wheels is indicated by the dotted lines 10 11 12, Figs. 3 and 1. The wheel 8 rides upon a pair of antifriction-rolls 13 and the wheel 9 upon a similar pair 14, whereby the cube or barrel may revolve about the axis 7, this being preferably the only movement of which the barrel is capable. By means of flanges upon the wheels 8 and 9 axial movement of the barrel is prevented, said flanges engaging the rolls 13 14, which are incapable of axial movement.

. sufficiently mixed.

As one means for revolving the barrel I secure to wheel 8 an annular gear 15, which surrounds this end of the barrel and is fixed to the rear side of said wheel behind the flange thereon. By means of an idle pinion 16 the gear is connected to a gear 17 the latter fixed upon a transverse shaft 18, and said shaft being driven by a transverse shaft 19, connected by gear 20 thereon and pinion 21 to crank-shaft 23 of an engine 24, fed by a boiler 25. If desired, the engine and boiler may be omitted and the mixer driven by a fiy-wheel or pulley 26, shown on shaft 23. Shaft 19. it will be observed, is connected to shaft 18 by means of a reversinggear comprising three miter-pinions 27, 28, and 29, the two latter being loose on shaft 18 and 27 being fast on shaft 19. Either pinion 28 29 (both constantly revolving in opposite directions) may be thrown into operative connection with shaft 18 at will by sliding in one direction or the other along the shaft a clutching-sleeve 30, which is splined on shaft 18 and operated by a lever 31, each of the pinions 28 29 having suitable provision to clutch said sleeve. Any other form of reversing-gear may be used, or the reversing-gear may be omitted and the engine driven in opposite directions, as desired, or in case the engine is omitted a suitable set of fast and loose pulleys with reversing-belts or belt mechanism may be substitu ted for the pulley 26. All of the described devices are preferably mounted upon a wagon body or truck 32, running upon four wheels 33. I

The materials to be mixed are put into a hopper 34 at the receiving end of the barrel and descend through the spout 35 of the hopper into an inclined chute 36, from which they enter through a round axial charging-opening 37 into the mixing-barrel. These ingredients, it will be understood, pass through the wheel 8, in which is formed the central opening 37 and enter the triangular opening in the cubiform barrel, which is formed by truncating its apex. This triangular opening is duplicated at the opposite apex of the barrel and is indicated by the lines 10 11 12 at Figs. 3 and 4. Said chute 36 is fixed upon the outer side of a vertical screen 38, supported by a framework 39, rising from the truck 32, and at its lower end terminates in an apron 40, which extends through the wheel-opening 37, so that the ingredients are deposited directly within the barrel and cannot foul the moving parts. Ingredients may be supplied from time to time as required, even though the mixing-barrel is in motion, since the chute 36 is in constant communication with the mixingbarrel.

By means of the power-driven gearing the barrel may be revolved until the materials are Then the motion of the barrel is reversed, the reversal being effected by means of the reversinggearing shown,

and by this reverse movement the contents of the barrel are automatically discharged. The discharge is effected by the operation of a set of three blades 42 43 44, fixed within the barrel and revolving therewith. While the barrel is revolving in one direction, these blades are wholly ineffective, except in so far as they assist in mixing the materials; but when the revolution of the barrel is reversed, as indicated by the arrow at Fig. 4, the blades act as scoops or buckets for discharging the mixed material at the end of the barrel opposite from the charging end. The blades are similar and symmetrically disposed about the axis of revolution 7, toward which axis they converge at their discharging ends, which are seen at Fig. 3 just within the inner edges 45 of wheel 9, a suitable spout 46 being fixed upon the framework in position to receive the discharge and conduct it away from the apparatus. It will be noticed that the upper edge of the spout 46 fits under a rim 47, Fig. 6, which surrounds the aperture 45, so as to insure against escape of material between the wheel and the spout.

Each blade or vane is preferably long and narrow and is secured edgewise to one side of the cubethat is, to one of the three sides that converge to the apex at the discharging end of the barrel. The blade 44 is secured to the side 4 and projects at about right angles therefrom and extends from the wheel 9 to the side 6 of the cube and extends about parallel to the adjoining side 3 0f the cube, forming in conjunction with the latter a pocket or bucket, which while at the lower part of the revolving barrel receives a portion of the contents thereof, and as the barrel revolves in the direction of the arrow, Fig. 4, rises with a movement analogous to that of the spoke of a wheel until the receiving end of the bucket is tilted above the dischaging end, whereupon the contents of the bucket flow out of the discharging end of the bucket and escape through the aperture 45 in the wheel 9 and are deposited in the spout 46, the bucket being entirely discharged by the time it reaches its highest position, in which position the blade is indicated at 43, Figs. 1 and 4. It will be observed that the inner end of the bucket is closed, since the inner end of the blade 44 abuts against the opposite side 6 of the cube, thereby preventing dripping or escape of material from this end of the bucket during the upward movement thereof. The three blades 42, 43, and 44 are similarly constructed and placed, and owing to their relative positions one is always picking up a charge of the contents of the barrel, while another is discharging, so that the discharge from the barrel is nearly continuous and sufficiently copious to empty it in a very short time. During the discharging operation the mixing, of course, is continued, which is a desideratum. The blades or buckets extend to the portions of the barrel which are most remote from the axis of revolution, so that the barrel is completely drained thereby, since these remote portions become lowermost when beneath the axis of revolution, and hence must receive even the dregs of the contents of the barrel, which hence are duly discharged by the movements of the buckets. The mouths of the buckets are indicated at 42, 43, and 44. The bucket blade or rib is provided with a retaining-ledge 51, which narrows or tapers toward the receiving end of the bucket. A shield 52 closes the discharging end of the barrel, but does not cover the discharging ends of the buckets.

It will be observed that the buckets are equidistant and that each is effective while traveling below the axis of revolution to scoop up some of the contents of the barrel and while traveling above said axis to discharge itself; that the sides 2, 3, and f of the barrel at the discharge end thereof converge toward the axis 7, said sides being substantially plane and forming corners 4:8, 4:9, and 50 at their junctions, the blades or vanes being near said corners; that the discharging-buckets extend to the exterior of the barrel; that each bucket is inclined to the axis of revolution 7, said axis being recumbent and preferably horizontal; that a portion of the barrels contents is discharged at each revolution in the direction of the arrow, Fig. 4; that the buckets discharge near the axis of revolution 7, thus making it practicable to employ a small opening 1O 11 12 in the barrel and a small opening f5 in the wheel 9 and conducing to compactness of the structure as well as to high efficiency for its size, and that either of the blades or scoops may be regarded as an interior revoluble discharging device, which may at will be rendered either effective to discharge the barrel or ineffective to discharge the same during the mixing operation.

The invention is not limited to the precise construction or form of discharging-buckets, barrel, &c., illustrated. Portions of the improvements may be used without others-as, for instance, one or more of the dischargingbuckets may be omitted.
